Thesis (Ph.D.) - Cairo University - Faculty of Agriculture - Department of Ornamental Horticulture
This study was conducted at the farm of the Medicinal and aromatic plants research department in Elkanater Elkhaireya, Kalyubeia Governorate, horticulture research Institute and prnamental horticulture department, agriculture Faculty, Cairo university, during the two successive seasons of 2012/2013 and 2013/2014. A field experiment was carried out to study the effect of cattle manure at the rates of 15 or 30 m3/fed., active dry yeast at 4 or 8 g/l water, humic substances at 1 l/fed., or combinations of these treatments, on the growth, seed yield, oil productivity, fatty acid content, germination of seeds and chemical constituents of evening primrose (oenothera biennis), compared to those obtained with the recommended dose of inorganic NPK fertilization [150 kg fed.-1 ammonium nitrate (33%), 60 kg fed.-1 calcium superphosphate (15.5%) and 60 kg fed.-1 potassium sulphate (48%)]. The obtained results showed that the pair cobination of cattle manure at the rate of 30 m3/fed. and humic substances 1L/fed. increased values of plant growth and seed yield parameters as well as chemical constituents (viz. chlorophyll a, b and carotenoid contents in fresh leaves and N, P, K, protein, total carbohydrate and total phenol contents in seeds). Also, the highest values of plant growth, yield parameters (viz. plant height, number of branches/plant, fresh and dry weights/plant, number of capsules/plant, seed yield/plant, seed yield/fed., oil percentage, oil yield per plant and oil yield per fed.) and chemical constituents (viz. chlorophyll a, b and carotenoid contents in fresh leaves and N, P, K, protein, carbohydrate, Þ-linolenic acid and total phenol content in seeds). were obtained with using the triple combination of cattle manure at 15 m3/fed., yeast at 8 g/L water and humic substances at 1 L/fed
